1 (.llaixn. wl. O-IZO) the front and-open at both rear This invention relates to an airf cooling attachment for electric fans and has for its object to provide an` improved device that may readily be attached to electric fans the airrset in `i5` motion by the fan-blades will be directed through an improved cooling structure.

Another object is to provide an improved device of the character set forth whereby the same may be attached to fan-structures of either the l0 stationary or oscillating types. so that in case of its attachment to the oscillating type may oacillate with the fan.

The invention is illustrated in the accompanying drawing. wherein.-

15 Fig. 1 shows an electric fan of the conventional oscillating type with my' improved attachment connected thereto. the structure being shown in side elevation.

Fig. 2 illustrates the same in front elevation,

20 and Fig. 3 shows the attachment on an enlarged n scale and in vertical section.

Referring to the drawing, the numeral l desig-v nates afan motor oi conventional vform in which s 86 .the motor itself. the fan-shaft l and fan-blades 1are,allmountedsoailtobeezascillatedwithre-v sibecttclthebase.

An annular band or-ring l isattached to the vertlcalfaceofthemotorattherearsideofthe l0 ian-blades. and my improved structure is carried of which partitions are suitably secured to the receptacle wall while the outer l edges thereof are attached to the outer shell.

The particular construction of thesepartitions 45 il is not essential so long astheir arrangemenp isy such as to provide a series of metal surfaces extending between the inner receptaclel and thev outer shell and to forni a series of air-passagesv il eatendingthroughtheshellfromtherearto of Ian, it 4 that the air driven by thefan-blades may pass through said pes'and out through the front ends thereof. i

The central receptacle Il, in the present instance. has a screw-cap I3 at its outer or front end so the interior of the same may be accessible.

In the present instance. I provide a plurality of arms il which extend horiaontally from the outer circumference of the shell l back past the fanblades and engage the band or ring l, whereby the shell with its central receptacle may be carried by saidring and held in front of the fanblades.

The receptacle Il is to contain a cooling medium, such as. ice, which will be held therein by means of the cap I3: and the ice will cool the wall of the receptacle and. by conduction. the partitionwalls Il,sothat theairpassing through the passages I2, will be chilled when it is disand front. so

charged at the front open ends of said passages. Y

receptacle may be accomplished with ease.

Having described my invention, I claim:- In an air-cooling attachment for electric fans the combination with a fan-structure including v a supporting pedestal, a motor mounted at the top 'of the pedestal. and a rotary fan having ra dially disposed Propeller type blades. of an Itunular shell concentrically disposed in spaced re"l latio'niniront ofthe fan bladesandopenatboth the front and rear sides thereof. .a mounting ring carried by the supporting pedestal in concentric spaced relation at the rear of the fan blades. tie

the i'an blades bridging the intervening space llne-- tween the mounting ring and acentrai coolilll 'receptacle in line'with the axis of the fan-blades and within lthe annular-shell. said receptacle hav .ing a movable cover at its front side and a series of radial partitions extending from' the annular shell-'tothe wall o t the central cooling receptacle to support the latter and toform a series of pascnsnmalnrmn.
